To all whom it may concern.-

Ee it known that I, HENRY FREDERICK AIL onsrus A BRAS$ARD, merchant, residing at 46'Vicar Lane, Bradford, England, have invented certain new and useful Improvements in Machines for Treating Silvers of Fiber and Yarn with Liquids; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it apper' tains to make and use the same.

My present invention relates to a machine for treating slivers of cotton, wool, and other fiber and yarn with liquids.

The machine is especially suitable for mercerizing cotton, but may be employed with equal profit for similar other purposes.

The treatment of the fiber takes place step by step, and to attain the end in view several baths and thereto-belonging mechanismsare arranged one after another, as now will be described and finally claimed.

In the accompanying drawings, Figure 1 is a longitudinal section, Fig. 2 a'plan view, and Fig. 3 a crosssection, of the machine. Fig. is a plan view of one of the endless grooved belts on a h scale, and Fig. 5 a cross-section of the 1 The slivers of fiber o. yarn l are wound up and placed conveniently near the end of the machine upon pegs 2, from whence the ends of said slivers are lead into the. grooves 3 of the endless belt 4. This belt consists oi flexible material and is placed in the bath 5 and runs over the rollers 6 upon shafts 7, journaled in boxes 8, sunk into the side parts 9 oi. the bath 5. The slivers 1 lie in the grooves 3 of belt a and are kept therein by the rollers 11, sothat the fibers cannot rise while passing through the alkaline liquid. The rollers 11 are supported on shafts 12 and journaled in boxes 13, likewise sunk into said side parts 9. As will be observed, the middle part of the endless belt is submerged iu'the alkaline liquid, but its ends are above the level of said liqiiid. The rollers 1] drive the endless belt at. After the slivers have been carried to their highest point by the endless belt at they are drawn over the cross-piece 14, provided with. the same number of grooves as the belt a. From here the slivers pass between the rollers 15 and 16, travel over the second crosspiece 17, likewise provided with acorrespond1 ing number of grooves, to the second endless belt 18, also grooved, and thence to the acid or neutralizing bath 1!).

The cross-pieces 14: and 17 are suitably fastoned to the side frames 20, firmly bolted to the side parts 9. The shaft 21 of roller 16 rests in journal-boxes of said frames'avithout covers, while the shaft 22 of rollenld is so duced end of the adjusting-screw 28 passes and is held therein by the well-known combination of a groove and a pin, so that when said screw is turned by its hand-wheel '29 in one or the other direction the shaft 22 receives more or less play. The screw passes through a nut 10, movablyplaced within the arm 30 of each frame 20, so that same may turn freely under all conditions. lach arm 30 is attached with one end to frame 20, while its bifurcated free end holds a rod.3l, attached to a weighted lever 32, turning upon a pin dilffastened to the side part 9, while its free end carries the shifting weight 34. The uppermost of rollers 6 is mounted with the crosspiece'l3 on detachable parts 350i the frames 20, so that the lower roller 16 may be removed.

The two upper rollers 36 of the endless belt 18 are journaled in arms of the frames 20, while the lower of rollers 36 is journaled in boxes 37, in line with the rollers =11, all receiving their motion from theshatt 38, rotated by the driving-shaft 39 by means of the spurwhecls 40 and 41. The bevel-wheels upon shaft 38 and those upon the shafts of the rollers 11 and the lower of rollers 36 are so pro-- portioned that theendless belts have the same velocity. The same must be said in regard to the rollers 15 and 16 belonging to the all aline bath 5, rollers 42 and 43 of the acid or neutralizing bath 19, rollers 44 and 45 of the washing-off bath 46, and the calendering-rollers 47 and 48, between which the slivers foo finally pass before they enter the receptacle 49. As the rollers 15 and 16 are larger in diameter than rollers 42, 43, 4i, and 45, the bevei-wheels and 51 are larger in proportion than bevel-wheels 52 and 53, driving the last-named pairs of rollers. The calendering-rollers have bevel-wheels 54 and 55 suitable to their diameter.

The shaft 39 is supported by brackets 56 'and the shaft 38 partly by brackets 56 and partly by brackets 5-7, Fig. 2, all secured to the side parts of the baths. The shaft 39 is journaled in the boxes 58 on top of the brackets 56 and receives its motion from a source not shown, while the smaller shaft 38 is journaled on the under side of'brackets 56 in boxes 59 and in brackets 57.

.Each bath is provided with a cook 60 to empty it and rests upon a stand 61.

As each of the two remaining baths is essentially the same in construction as bath 5, corresponding parts of said baths are marked with like reference-numbers. Existing differences worth mentioning are that in baths 19 and 46 only three of rollers 11 are employed against four in bath 5; also, an endless belt like 18 is absent in bath l9 and its place is taken up in bath 46 by the calendering-rollers 47 and t8 and the two cross-pieces 62 and 63. e

The accompanying drawings show at a glance how the slivers pass from one bath to another in succession and "how they finally are collected in tiie'recegitacle 49, so that a detailed explantion is made superfluous.

In a machine for treatingslivers of fiber- 1 adjusting said press-rollers, means for rotating the holding-down rollers and the lower press-rollers, grooved cross-bars adjacent to the lower press-rollers, means for emptying said baths,stands supporting the baths, calendering-rollers connected with the washing-off bath and means for rotating the lower calendering-roller.

2.

4. In a machine for treating slivers of fiber and yarn with liquids the combination of a washing-off bath, an endless longitudinallygrooved belt therein, rollers carrying said belt, larger rollers holding down said slivers in said grooves and in, the liquid, frames for supporting the press-rollers, means for rotat- 9 ing said press-rollers; comprisingsliding covers for the upper prcss-roller bearings, adjusting-screws, arms pivotally attached to said frames and carrying the nuts for said screws, rods connected with said arms and weighted levers, bevel-wheels upon the shafts of the driven rollers, bevel-wheels upon the driving-shafts, brackets to support said driving-shaftsg grooved cross bars adjacent to the lower press-roller, calender-iug-rollers, grooved cross-bars adjacent to the lower calendering-roller, and means for driving the latter roller.

In. testimony that I claim the foregoing as my invention 1 have signed my name in presence of two subscribing witnesses.
